How to increase diamond recovery using froth separation?
A new study reveals innovative methods to improve the efficiency of froth separation for diamond-bearing kimberlites. Researchers have proposed solutions that could reduce diamond losses by up to 20%!
🔹 Key Findings:
1. Restoring diamond hydrophobicity by removing mineral coatings through combined treatment: thermal, ultrasonic, electrochemical, and reagent conditioning.
2. Optimal temperature regime:
- heating the feed to 85–90°C for preparation;
- conditioning at 30–40°C;
- separation at 20–24°C.
3. Collector optimization:
- adding low- and medium-molecular fractions increases collector efficiency by 16%;
- ketone additives enhance adhesion activity up to 87%.
4. Closed-loop water recycling with clarification reduces reagent consumption by 8% without compromising concentrate quality.
